`VELOCIPEDl SPECIFICATION forming part of Letters Patent No. 435,493, dated September 2, 1890. Application filed January l0, l`890. Serial No. 336,506. (No 121101.)

To all whom it may concern:

Be it known that I, SPENCER GAEwoon, a citizen of the United States, residing at Milford Centre, in the county of Union and State of Ohio, have invented acertain new and useful Improvements in Vehicles, of which the following is a specification.

My invention relates to improvements in vehicles adapted to be drawn forward by a horse or other animal or propelled in any suitable and' desirable manner.

The objects of my invention are to provide a construction in vehicles by which the friction is reduced to the minimum, to so construct and arrange the parts that the weight of the carriage and its occupants is distributed so as to secure the best possible results in the propulsion of the vehicle, and to permit the same to pass easily over rough and uneven surfaces, obstacles, or obstructions without damage to the operating parts.

My invention consists in the constructions and combinations of parts hereinafter dcscribed, and set forth in the claims. j

In the accompanying drawings, Figure l is a longitudinal sectional View, in elevation, of a device embodying my invention. Fig. 2 is a plan viewrand Fig. 3 is a front elevation, of the same.

Like parts are represented by similar letters of reference throughout the several views.

In the accompanying drawings, A A represent the side bars of the main frame or body of a vehicle. Pivoted to the sides of the frame A, at a, is a diameter-arm B, which carries at its upper extremity a cross-bar B, to which are journaied friction or bearing Wheels B2. .Iournaled on the arm B on a suitable spindle B3 is a supporting-wheel B5. These supporting and bearing wheels B2, B2, and B5 are each suitably grooved on their periphery or provided with side flanges adapted to tit over a large traveling ring or Wheel O, which maybe provided on its inner side with an inside tire of rubber. This ring or wheel O is preferably made of rounded iron or steel, and travels on the ground as the vehicle is propelled.

Pivoted to the side of the frame A, at a', are small supporting-arms b, provided at their outer extremities with suitable journals b',

on which are adapted to turn lock-wheels b2,

also provided with groovcd or flanged periph-V eries adapted to engage with and travel within the ground rings-or Wheels C.

Immediately following the large ground or traveling Wheels C,I provide a smaller pair of traveling Wheels I), in which are arranged bearing-wheels c and c', grooved on their periphery and adapted to fit Within the ground or traveling wheel I) and supported at the extremities of a pivoted arm c2. Each of these arms c2 is pivoted to a projection c3,A forming an extension of and pivoted at c to the main frame A.

The supporting diametenarm c2 is provided at one side with a loop -guide or baleguard c5,which passes loosely through the end connectinglink c7, which is attached or connected at its other end to the spindle or trunnion b of the lock-wheel b2. iiy this conl struction it will be seen that the carriage body or frame A A is supported at each side on the bearing and supporting wheels, which travel within the ground or traveling Wheels. The rear ground or traveling wheels D are adapted to track witlrthe forward groundwheels when the vehicle is traveling in a straight line, and adapted to assume an angular position with reference to the forward traveling-wheels when the vehicle is changing direction, the bearing and supporting wheels in the front and rear ground Wheels being con nected together through the medium of theframe, as well as the connecting-links c7.

rlo provide a more rigid connection for the supporting-arm B, to insure the proper tracking of the respective lock and supporting wheels, I provide a brace-connection (l, which is pivoted to the supporting-arm B at the center of its height, as shown at d', and connected at the other end to the trunnion or spindle Z9 of the lock-wheel b2 or to side bars A for a two-wheeled vehicle, the point CZ being located at the center of the ground or traveling Wheel O.

On each side of the frame A,I provide suitable supporting or sprocket Wheels e c, over which I pass a suitable belt or chain e', and to one side of this belt or chain I attach, by means of a suitable projection c2, a connecting-bar e3. This connecting-bar e3 is pivoted IOO at its other end to the trunnion b'. Extending from each of the endless chains c are operating ropes or chains c5, which are connected to the endless chains e' on the opposite side of the supporting-Wheels from the bar e3. These operating-ropes e5 are connected at their opposite ends to a shaft c7, by which they are adapted to be wound, the said shaft e7 being provided with asuitablehandwheel e and a pawl and ratchet cl2, and being journaled vertically in the forward end of the vehicle frame or body, as shown.

Connected to each of the operating ropes or chains e5, at a point between the shaft e7 and the endless chain e', I attach a rope or cord f, which extends over a suitable bolt or sheave f on the frame A A, and is attached to the supporting-arm B above the brace-connection d. By the construction as thus described when the vehicle is drawn forwardly a revolution of the shaft e7 will cause the operating-ropes e5 to be Wound thereon, which will in turn revolve the endless chains c upon their supporting-wheels and force the lockwheels b2 upwardly and backwardly in the forward ground-wheel C. These bearing-wheels i b2 being pivotally connected to the frame and supporting-arm B will aid the said frame to be elevated and thrown forward, as indicated in dotted lines. The diameter-arms B and c2 being pivoted to the frame and to the supporting-wheels B5 and b2, respectively, at dit'- ferent points, thc said supporting-wheels will be moved forwardly and upwardly Within the respective ground-wheels, which will carry the bearing-wheels B2 and c backwardly and downwardly in said ground-wheels, as indicated in dotted lines in Fig. l. In this position the Vehicle is adapted to be operated, propelled forwardly by suitable means connected to the vehicle or drawn by any suitable inotive power. The weight of the frame and vehicle is thus brought against the rim of the respective ground-wheelsin front of a vertical line passing through the center thereof and at some distance above the contactpoint between the bearing-wheels and the said ground-wheels. The respective parts will be retained in this position by the arrangement ot` the respective pivoted arms and the connecting-chains, together with the lock or bearing wheels b2, which press against the opposite side of the forward ground-wheels C. In this position the weight of the vehicle will be supported within the respective ground-wheels at dilferent points on opposite sides of the center ofthe contactpoints. These ground-wheels from their nature and construction have a certain amount of ilexibility, which will prevent the transmission of shock or jar occasioned from traversing rough or uneven surfaces to the frame 01 vehicle-body. This position of the parts will also bring the weight of the Vehicle in such position on the ground-wheels as to offer the least resistance in the propulsion ot' the vehicle, and to aid rather than retard the same.

It is obvious that instead of cross-bars B and the bearing-Wheels B2 B2 a single bearingwheel may be pivoted to the extremity of the supporting-arm B, the same as in the rear ground-wheel. Other modifications may be made without departing from the spirit of my invention. If desired, the frame sidebarsA may be connected with the diameter-bars c2 below the centers of the Wheels c.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination, with a ground-wheel having the internal traveling, bearing, and supporting wheels, as described, j ournaled on the supporting-arm pivoted to the main frame, of an endless chain supported on said frame and connected to one of said bearing-wheels, and means for operating said chain to force said bearing-wheels against the inner periphery of the ground-wheel,substantially as specified.

2. The combination, with the main frame and groundwhee],of the pivoted arms B and b, having the supporting-wheels B5 and b2 journaled thereon and adapted to travel in said ground-wheel,a bearing-wheel on one of said arms, also traveling in said ground-wheel diametrically opposite one of said supportingwheels, and a brace connecting` the respective supporting-arms, the said brace heilig piv'oted to one of said arms at the center of the groundwheel, substantiallyv as specified.

3. The combiuation,with a Vehicle, of a front. ground-Wheel having the supporting and bearing wheels, as described, and a rear groundwheel also provided with suitable supporting and bearing wheels, the supporting and bearing wheels in the rear ground-wheel being so connected to the vehicle-frame as to permit the rear ground-wheel to assume an angular position with reference to the front ground- Wheel, substantially as specified.

4. The combination, with the main frame, of the ground-wheels C, supporting-arms B and b,supportingwl1eels Band b2, brace connections (l, endless chains e', connecting-bar e3, operating-ropes e5 and f, and the handwheel e, arranged and operated substantially as speciiied.

5. The combination, with the main frame having the forward ground-wheels, pivoted supporting-arms, and internal bearing and supporting wheels, as described, of the rear ground-wheel having a supporting-arm with bearing and supporting Wheels, said arm being provided with a yoke pivotally connected to one of the supporting wheels of the front ground-wheel, substantially as specified.
